Tungsten Dashboard allows you to monitor and operate the clusters in real time.
This browser-based web application gets data from a purpose-built backend, which is designed to efficiently gather data from the cluster nodes independently of the browser requests.
The Dashboard backend serves HTML and React JavaScript to the browser via a built-in JVM-hosted Jetty Server.
The browser-based REACT JavaScript frontend then uses an API to authenticate the user. To provide a smooth user experience, the frontend forms a websocket connection with the backend server to get and display cluster information. For security, each websocket connection must have a valid user login token behind it.
The Dashboard requires you to login with a user account before you can see or act on the clusters themselves.
For first time installations, either the install.pl script prompts you for the credentials,
or the credentials are included in your helm deployment configuration.
To create additional users, and to get started, see Section 4.2, “Create your own user account”
Note
The Dashboard uses the browser's Local Storage feature to save non-sensitive metadata (about expanded services, expanded sidebar, and temporary access token). Please make sure your browser allows storing data using Local Storage or Cookies.
